This application claims the benefit of U.S. Patent Application Ser. No. 63/075,221, which was filed on Sep. 7, 2020, and is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure relates to implementations of a boat propulsion and guidance system.

BACKGROUND

Boats are small to medium sized sailing vessels of various types, shapes, etc. For example, FIG. 7 illustrates an example existing boat such as a typical offshore fishing boat. Boats often include a motorized configuration for propelling and/or maneuvering the boat. For example, some boats usually include an outboard motor for propelling and one or more thruster motors for maneuvering or steering. Other boats usually include one or more main engines for propelling and maneuvering, which are usually capable of high speeds, and may also include one or more thruster devices for more controllable maneuvering, such as at lower speeds.

However, the motors are usually mounted outside the body or hull of the boat and are too noisy to operate while trying to fish or otherwise be quiet while boating. Also, the motors are usually separate devices that have to be separately operated or controlled. Furthermore, the existing configurations include sharp turns or radii that make the configurations inefficient. Additionally, the existing configurations are prone to fouling up or bio-fouling when not in use from the growth of biological material such as algae, weeds, etc. on the exposed motors and other components.

Moreover, existing thruster designs are mounted inside the hull of the boat (inboard) or outside the hull (outboard). Inboard thruster designs are used to force a section of the boat in a particular direction for steering or maneuvering purposes. Some previous designs have exterior nozzles to vector the force. The nozzles and other designs have many sharp turns or radii that hinder their efficiency. Outboard designs usually have articulated directional control and have to be stowed during high speed operation or placed in a position that will not encounter turbulence.

DETAILED DESCRIPTION

Implementations of a boat propulsion and guidance system are provided. In some implementations, the boat propulsion and guidance system comprises one or more conduits and propulsion devices. In some implementations, the boat propulsion and guidance system may further comprise one or more valve devices. In some implementations, the boat propulsion and guidance system may further comprise a controller.

In some implementations, the boat propulsion and guidance system is configured to steer, maneuver, and/or otherwise propel a boat.

In some implementations, the boat propulsion and guidance system is configured to steer, maneuver, and/or otherwise propel a boat as a single, combined, and/or integrated system of components that can be singly or commonly operated and/or controlled.

In some implementations, the boat propulsion and guidance system is configured to position on a boat and operate quietly to the surrounding environment of the boat such that the boat propulsion and guidance system can be used while fishing or otherwise boating while needing to be quiet.

In some implementations, the boat propulsion and guidance system is configured to be more efficient by providing a generally straight flow of propulsion without sharp turns or radii, such as by comprising generally straight conduit.

In some implementations, the boat propulsion and guidance system is configured to close up when not in use to prevent the undesirable growth of biological material or bio-fouling on components of the boat propulsion and guidance system, such as by algae, weeds, etc.

In some implementations, the boat propulsion and guidance system is configured to move (e.g., steer, maneuver, and/or otherwise propel) a boat in one or more directions, such as forward, backward, leftward, rightward, and/or sideways. In some implementations, the boat propulsion and guidance system may be configured to move a boat in a 360-degree zero turn radius motion.

In some implementations, the boat propulsion and guidance system may be configured to position a boat by dynamic anchoring to cause the boat to remain in a desired position in the water.

In some implementations, the boat propulsion and guidance system may be configured to be installed and/or used as a primary and/or sole propulsion and guidance system of a boat. In some implementations, the boat propulsion and guidance system may be configured to be installed and/or used in addition to another propulsion device of a boat.

In some implementations, the boat propulsion and guidance system is configured to be used on any suitable configuration of boat, such as a single hull boat or a multiple hull boat, such as a catamaran, trimaran, etc.

In some implementations, the boat propulsion and guidance system may be configured to receive global positioning system (GPS) coordinate inputs for controlling the operation of the boat propulsion and guidance system.

In some implementations, the boat propulsion and guidance system may be configured to receive magnetometer and/or accelerometer inputs for controlling the operation of the boat propulsion and guidance system.

In some implementations, the boat propulsion and guidance system may be configured to execute proportional, integral, derivative software for controlling the operation of the boat propulsion and guidance system.

In some implementations, the boat propulsion and guidance system may be configured to use analog controls to produce force in any direction by using varying amounts of propulsion in any of four or more directions.

In some implementations, a method of using the boat propulsion and guidance system comprises installing the boat propulsion and guidance system to a boat and operating the boat propulsion and guidance system to move (e.g., steer, maneuver, and/or otherwise propel) the boat in one or more directions. In some implementations, the method may further comprise operating the boat propulsion and guidance system to dynamically anchor the boat to remain in a desired position in the water.

Boats are small to medium sized sailing vessels of various types, shapes, etc. For example, FIG. 7 illustrates an example existing boat 10 such as a typical offshore fishing boat. Boats 10 often include a motorized configuration for propelling and/or maneuvering the boat. For example, as shown in FIG. 7, some boats 10 usually include an outboard motor for propelling and one or more thruster motors for maneuvering or steering. Other boats usually include one or more main engines for propelling and maneuvering, which are usually capable of high speeds, and may also include one or more thruster devices for more controllable maneuvering, such as at lower speeds.

As shown in FIG. 7, the motors are usually mounted outside the body or hull of the boat 10 and are too noisy to operate while trying to fish or otherwise be quiet while boating. Also, the motors are usually separate devices that have to be separately operated or controlled. As also shown in FIG. 7, the sides or portions of a boat 10 are known as the bow or front, the stern or rear, the port or left side, and the starboard or right side.

The existing configurations for propelling and/or maneuvering a boat 10 include sharp turns or radii that make the configurations inefficient. Additionally, the existing configurations are prone to fouling up or bio-fouling when not in use from the growth of biological material such as algae, weeds, etc. on the exposed motors and other components.

Moreover, existing thruster designs are mounted inside the hull of the boat (inboard) or outside the hull (outboard). Inboard thruster designs are used to force a section of the boat in a particular direction for steering or maneuvering purposes. Some previous designs have exterior nozzles to vector the force. The nozzles and other designs have many sharp turns or radii that hinder their efficiency. Outboard designs usually have articulated directional control and have to be stowed during high speed operation or placed in a position that will not encounter turbulence.

The boat 10 of FIG. 7 is an example of any suitable boat for which the boat propulsion and guidance system 100 can be used, as described below. However, as will be understood by one skilled in the art based on the present disclosure, the boat propulsion and guidance system 100 can be used for any other of numerous suitable variations of boats.

FIGS. 1, 2, 3, 4, 5, 6A-6C, and 8 illustrate implementations of a boat propulsion and guidance system according to the present disclosure.

With respect to the above described features of the boat propulsion and guidance system 100, FIGS. 6A-6C illustrate an implementation of a boat propulsion and guidance system 100 (100A) according to the present disclosure. As shown in FIG. 6A, in some implementations, the boat propulsion and guidance system 100 comprises a pump 122 with an attached motor 121, a right and a left intake port 111 a, a right and a left exhaust port 111 b, two differential valves 134, and an actuator 135 that controls the differential valves 134. In some implementations, the boat propulsion and guidance system 100 further comprises one or more conduits 110 and/or controllers 140.

As shown in FIG. 6A, in some implementations, the right and the left water intake ports 111 a are mounted at or about −45 degrees and +45 degrees respectively from the forward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat.

In some implementations, the boat propulsion and guidance system 100 is thereby configured to allow a cross-flow of the propulsion that produces a forward and lateral (e.g., leftward) movement of a boat.

As shown in FIGS. 6A and 6C, in some implementations, the differential valves 134 are configured to allow the flow of propulsion through the right (or starboard side) intake port 111 a and the left (or port side) exhaust port 111 b when the actuator 135 is extended, retracted, or otherwise suitably activated. In some implementations, the differential valves 134 are configured to prevent the flow of propulsion through the left intake port 111 a and the right exhaust port 111 b when the actuator 135 is extended, retracted, or otherwise suitably activated.

In some implementations, the boat propulsion and guidance system 100 is thereby configured to allow propulsion, such as water, air, etc. propelled by the pump 122 and the motor 121, to flow from the right intake port 111 a to the left exhaust port 111 b when the actuator 135 is extended, retracted, or otherwise suitably activated. In some implementations, the boat propulsion and guidance system 100 is thereby configured to allow a cross-flow of the propulsion that produces a forward and lateral (e.g., rightward) movement of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to operate by the controller 140 receiving global positioning system (GPS) coordinate inputs. In some implementations, the GPS coordinate inputs may be based on a desired location or destination.

In some implementations, the boat propulsion and guidance system 100 is configured to operate by the controller 140 controlling the actuator 135 to control propulsion flow through the ports 111 a, 111 b by controlling the differential valves 134. In some implementations, the boat propulsion and guidance system 100 is thereby configured to steer a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to operate by the controller 140 controlling the motor 121 to control propulsion flow through the ports 111 a, 111 b by controlling the pump 122. In some implementations, the boat propulsion and guidance system 100 is thereby configured to control the speed of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to control the speed of the boat based on the distance to the desired location. For example, in some implementations, the boat propulsion and guidance system 100 is configured to control the speed of the boat such that the shorter the distance to the desired location, the lower the speed of the boat.

In some implementations, the boat propulsion and guidance system 100 may be configured to operate to control a boat in any other suitable way.

With respect to the above described features of the boat propulsion and guidance system 100, FIG. 1 illustrates another implementation of a boat propulsion and guidance system 100 (100B) according to the present disclosure. As shown in FIG. 1, in some implementations, the boat propulsion and guidance system 100 comprises a first conduit 110 c having a first port 111 c 1 and a second port 111 c 2 and a second conduit 110 d having a first port 111 d 1 and a second port 111 d 2.

In some implementations, the boat propulsion and guidance system 100 comprises first conduit valves 131 c 1, 131 c 2 and second conduit valves 131 d 1, 131 d 2. In some implementations, the boat propulsion and guidance system 100 comprises first conduit thruster devices 120 c 1, 120 c 2 and second conduit thruster devices 120 d 1, 120 d 2. In some implementations, the boat propulsion and guidance system 100 further comprises one or more controllers 140.

As shown in FIG. 1, in some implementations, the first ports 111 c 1, 111 d 1 are mounted arranged in an outward angle (e.g., of or about −45 degrees and +45 degrees) respectively on opposite sides of the forward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat. Similarly, in some implementations, the second ports 111 c 2, 111 d 2 are mounted arranged in an outward angle (e.g., of or about −45 degrees and +45 degrees) respectively on opposite sides of the rearward lengthwise extending center line of the boat propulsion and guidance system 100 and/or the boat.

As shown in FIG. 1, in some implementations, the ports 111 c 1, 111 d 1, 111 c 2, 111 d 2 are mounted as described such that the first and second conduits 110 c, 110 d extend diagonally between the first ports 111 c 1, 111 d 1 and the second ports 111 c 2, 111 d 2 respectively, such as in an X-shaped or cross configuration. For example, in some implementations, the first conduit 110 c extends from the first port 111 c 1 at the front (bow) left (port) to the second port 111 c 2 at the back (stern) right (starboard) and the second conduit 110 d extends from the first port 111 d 1 at the front right to the second port 111 d 2 at the back left when the boat propulsion and guidance system 100 is used on a boat.

In some implementations, the ports 111 c 1, 111 d 1, 111 c 2, 111 d 2 may be positioned in any other suitable configuration.

In some implementations, the conduits 110 c, 110 d may be connected together. For example, in some implementations, the conduits 110 c, 110 d may be attached together where the conduits 110 c, 110 d cross in the cross configuration, such as at or near the lengthwise center of the conduits 110 c, 110 d.

In some implementations, the conduits 110 c, 110 d may be attached together but not inter-connected or cross-connected to allow the flow of propulsion between the conduits 110 c, 110 d.

As shown in FIG. 1, in some implementations, the conduits 110 c, 110 d may be connected together such that the conduits 110 c, 110 d are inter-connected or cross-connected. For example, in some implementations, the conduits 110 c, 110 d may be connected such that propulsion can flow between the conduits 110 c, 110 d.

In some implementations, the conduits 110 c, 110 d may be cross-connected such that propulsion can flow from a port 111 c 1, 111 c 2 of the first conduit 110 c to a port 111 d 1, 111 d 2 of the second conduit 110 d. In some implementations, the conduits 110 c, 110 d may be cross-connected such that propulsion can flow from a port 111 d 1, 111 d 2 of the second conduit 110 d to a port 111 c 1, 111 c 2 of the first conduit 110 c.

In some implementations, the conduits 110 c, 110 d may be connected or attached together in any other suitable configuration.

In some implementations, the boat propulsion and guidance system 100 may alternately comprise a multi-section, multi-port conduit (e.g., similar to the boat propulsion and guidance system 100C described below for FIG. 2) having the above described features and configuration of the conduits 110 c, 110 d.

As shown in FIG. 1, in some implementations, the first conduit valves 131 c 1, 131 c 2 are positioned at or adjacent to the first conduit ports 111 c 1, 111 c 2 respectively. In some implementations, the second conduit valves 131 d 1, 131 d 2 are positioned at or adjacent to the second conduit ports 111 d 1, 111 d 2 respectively. For example, in some implementations, the valves 131 c 1, 131 c 2, 131 d 1, 131 d 2 may be positioned immediately inside the ports 111 c 1, 111 c 2, 111 d 1, 111 d 2 respectively.

In some implementations, the valves 131 c 1, 131 c 2, 131 d 1, 131 d 2 may be positioned in any other suitable location to control the flow of propulsion through the ports 111 c 1, 111 c 2, 111 d 1, 111 d 2 and/or the conduits 110 c, 110 d respectively.

In some implementations, the first conduit thruster devices 120 c 1, 120 c 2 may be in any suitable position of the first conduit 110 c adjacent to the first conduit ports 111 c 1, 111 c 2 respectively. In some implementations, the second conduit thruster devices 120 d 1, 120 d 2 may be in any suitable position of the second conduit 110 d adjacent to the second conduit ports 111 d 1, 111 d 2 respectively.

For example, as shown in FIG. 1, in some implementations, the thruster devices 120 c 1, 120 c 2, 120 d 1, 120 d 2 may be positioned adjacent to the valves 131 c 1, 131 c 2, 131 d 1, 131 d 2 respectively opposite the ports 111 c 1, 111 c 2, 111 d 1, 111 d 2. In some implementations, the thruster devices 120 c 1, 120 c 2, 120 d 1, 120 d 2 can thereby be enclosed in the conduits 110 c, 110 d when the valves 131 c 1, 131 c 2, 131 d 1, 131 d 2 are closed, such as to prevent exposure and biological fouling when the boat propulsion and guidance system 100 is not in operation.

In some implementations, the thruster devices 120 c 1, 120 c 2, 120 d 1, 120 d 2 are further positioned such that the thruster devices 120 c 1, 120 c 2, 120 d 1, 120 d 2 can control the direction and/or speed of propulsion, such as moving water, through the conduits 110 c, 110 d and ports 111 c 1, 111 c 2, 111 d 1, 111 d 2.

In some implementations, the boat propulsion and guidance system 100 is configured to use the force of water displacement and/or the force of pressure against the outside water to produce motion of a boat in a desired direction. For example, in some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from the left front port 111 c 1 to the right rear port 111 c 2 to produce a forward and left (port) motion of the boat. In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from the right front port 111 d 1 to the left rear port 111 d 2 to produce a forward and right (starboard) motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from both right ports 111 d 1, 111 c 2 to both left ports 111 c 1, 111 d 2 to produce a rightward sideways motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from both front ports 111 c 1, 111 d 1 to both rear ports 111 c 2, 111 d 2 to produce a forward motion of the boat. In some implementations, the boat propulsion and guidance system 100 is configured to propel water flow from both rear ports 111 c 2, 111 d 2 to both front ports 111 c 1, 111 d 1 to produce a reverse motion of the boat.

In some implementations, the boat propulsion and guidance system 100 is configured to use the controller 140 comprising analog motor controls with a central controller to produce force in any desired direction. In some implementations, the force can provide motion in any suitable direction. In some implementations, the force can provide dynamic anchoring that causes a boat to remain in a desired position while compensating for outside forces.

In some implementations, the boat propulsion and guidance system 100 is configured to control the thruster devices 120 c 1, 120 c 2, 120 d 1, 120 d 2 by a magnetometer and/or accelerometer input or by global positioning system (GPS) signals. In some implementations, the boat propulsion and guidance system 100 is configured to use proportional, integral, derivative software to smooth out the input signals to produce a steady, accurate movement of a boat.

In some implementations, the boat propulsion and guidance system 100 is configured to operate more efficiently by providing a generally straight flow of propulsion without sharp turns or radii.

In some implementations, the boat propulsion and guidance system 100 is configured to close the valves 131 c 1, 131 c 2, 131 d 1, 131 d 2 when not in use to prevent the growth of biologic material or bio-fouling, such as to the thruster devices 120 c 1, 120 c 2, 120 d 1, 120 d 2 and/or other components of the boat propulsion and guidance system 100.
